1.11 Total area on campus  for water absorption besides the forest and planted vegetation

Besides the forested and planted vegetation areas, several other zones within Politeknik Sultan Salahuddin Abdul Aziz Shah (PSA) contribute significantly to water absorption and sustainable water management. These include open green spaces, sports fields, grass-covered parking areas, and permeable walkways that allow rainwater to naturally infiltrate the ground. The landscaped gardens around academic blocks and hostels also act as natural catchment zones, reducing surface runoff and minimizing the risk of flash floods.

Additionally, rainwater harvesting systems and soakaway pits in selected areas help recharge groundwater and reduce dependence on treated water for landscape maintenance. Drainage designs within the campus are structured to channel rainwater toward vegetated zones, ensuring efficient absorption rather than rapid discharge. These initiatives not only support water conservation but also align with PSA’s SmartGreen and SDG 6 (Clean Water and Sanitation) efforts, promoting an environmentally resilient campus ecosystem.
